- Description: The effectiveness of using a teaching strategy, based on analogies for direct current electric circuits, to attempt to address first-year underprepared university students was investigated. The study consisted of 53 participants drawn from the Faculty of Health Sciences at Nelson Mandela University. A quantitative research design was adopted using the “Determining and Interpreting Resistive Electric Circuits Concepts Test” (DIRECT) version 1.2 as a research instrument. The DIRECT is a 29-item multiple-choice test with only one correct answer in each question. The DIRECT was modified to further probe students’ confidence levels in their answers. The instrument served as a pre-test prior to the start of the formal lessons on direct current electric circuits. At the end of a five-week treatment period, the same instrument was administered to all participants as a post-test. The statistical analysis and interpretation of the preand post-test data were conducted using Software Package for Social Sciences (SPSS) version 23 and STATISTICA version 12. In answering the main research question (How can a misconception-based module, using analogies,positively influence(or not)academically under-prepared first-year non-major Physics students’ conceptual understanding of direct current(DC)electricalcircuits?)and sub-questions thereof, the students’ mean scores between the pre-and posttest were calculate and compared using t-test at a significant level of 0.05. The results revealed a statistically significant difference between the preand post-test mean scores. The pre-test mean score was 22.24 with a standard deviation of 8.07. The post-test mean score was 38.68 with a standard deviation of 13.93. The mean score difference between the post-test and pre-test was 16.44 with a standard deviation of 13.82 at p-value less than 0.05. The results from the pre-test suggest that students held very strong alternative conceptions on direct current electric circuits. The post-test results also revealed that some alternative conceptions were still held onto after the intervention. There wasno statistical significant difference found between the students’ correct answers and their confidence levels. The quantitative analysis of the results suggested that there is a positive change between the post-testmean score and pre-test mean score and this change is statistically significant (p < 0.05). The results showed sufficient evidence to conclude that analogies-based teaching strategy was a vieffective means of reducing the number of alternative conceptions the students held about direct current electric circuits. The study recommended the need to ascertain out what the students felt about the improvement of their understanding of direct current electric circuits concepts. The study suggested a qualitative research methodology as an area for future research.

- Description: In many developing nations, the majority of poor people live in rural areas. Yet, most of them do not have access to financial services needed to sustain their living standards. Poverty remains high in many developing nations, despite numerous non-government and government efforts to alleviate poverty through microfinance. Further, poor people are not unique to rural areas; they are present in urban areas too. Poverty remains prevalent and much remains to be done to improve the quality of life for the poor people. This study examines the role of Microfinance Institutions (MFIs) in poverty alleviation for both rural and urban areas of Limpopo Province. This study was aimed at investigating how MFIs are benefiting low-income earners in the rural and urban areas of Limpopo Province. Mopani District in Limpopo Province was the study area. Forty five MFIs clients were interviewed as well as ten MFIs in the. This study adopted a mixed research approach. Primary data was collected through structured and semi-structured questionnaires, while secondary data was collected from published and unpublished materials. The findings of the study revealed that MFIs operating in Mopani District only provide credit facilities to their clients. The services are provided to all gender, salary earners, pensioners and residents of both rural and urban areas. The interest charges on the credit ranged from 5% to 40%. The collateral security required was certified ID, payslip, bankcard, and proof of residence and personal assets. The study established that those clients that accessed loans from MFIs were able to improve their standard of living through start up and expanding their businesses, paying school fees, building and improving their house and affording private health facilities. The research found out that there are challenges faced by both MFIs and MFIs clients. MFIs indicated that they faced challenges such as increased competition, lack of information about the client, profit performance and attracting low –income clients. However, the clients indicated that MFIs charge high interest rates. The respondents recommend that MFIs could lessen interest rate, increase on the amount given as loans to their clients and assess repayment capabilities before offering loans. For MFIs client’s respondents recommend that to improve the standard of living clients could get investment opportunities.
